Using a pen instead of a mouse includes also using a different pointer. I made a new pointer and I use the left version. Download the right or left version or both. Create in [drive:]\OS2\pointers a new directory, eg "Big Pen Pointer Color" and unzip the file (right version) in it. The left version goes the same way, only the directory is now called "Big Left Hand Pen Pointer Color", in style as already exists in the \OS2\pointers. Unzip the file in this directory (left version).

In the mouse settings pointer page you can load the new set, this will be active immediately.

These are the pointers of the left version;
example of the left-hand version
These are the pointers of the right version;
